Hi,
I need do this modification in a Samsung S9 for my project.
I will put S9 inside a box and only space out of box is the USB-C for charging.
When battery over, I would like to plug the charge cable and the smartphone turn on again without press any button.
I search a lot, read stackoverflow/quora altought without sucess.
At this moment the S9 is rooted.
Someone could help me ?
This is not feasible by SW Mod.
Most likely you need to modify the FW boot loader on the MOBO.
Possibly it is momething to be implemented in the TWRP but also this rely in pressing some buttons on the mobile.

Hi,
I want to update my ROM from a standard WM5 to WM5SE rev 5.0. Following instructions, I downgraded with the button ROM to let me CID unlock my G3 Jammin. The butotn ROM installed, but when it reset it would not boot and both the red and blue lights would flash together, the screen would flash on, and then it would shut off.
This pattern is repeated every couple of second and doesn't stop until I pull the USB cable out, after which it repeats once more then switches off. I can't turn the phone back on with the power button. From here I can get back into the locked cycle by powering on with the USB cable plugged in (back into reset cycle), or into windows with the mains power cable (see below).
I think this means that the problem is related to my USB cable being plugged in. When I put the mains power cable in, the PDA will boot into windows. Related to this is what I think may be the main culprit. In setting, Windows says the battery is on 0%!!! Even the mains power cable doesn't seem to ever charge it, so I think it must be a software problem related to the ROM. Inceidentally, I recall that I had to softreset near the end of Button ROM's install, perhaps this is part of the problem...
Now I can reinsert the USB cable only during the Windows boot process, which as mentioned has to be initiated with the mains power cord, ie. I swap over half way through. If I change from mains power to USB after Windows has fully booted then the phone resets and the above reseting cycle occurs again.
Once Windows is fully booted with the USB cable in everything is stable and Activesync detects the phone. The problem is that when I try to reinstall a stable ROM, the update software throws the following error: Error [220] mains battery power. So the software I believe is reading that the battery is less than 50% (ie. probabaly thinks there is 0 charge left) and I can't reinstall a new ROM!!
The other thing to note is that I can get into bootloader mode with the mains power cable, but as soon as I try to switch over to the USB cable, the phone resets and it again gets locked into the perpetual reset cycle.
Please help me!! Any ideas are appreciated.
Gavin.
Hi,
Found this: http://forum.xda-developers.com/showpost.php?p=1216580&postcount=23
Seems like a similar problem. He solved it by replacing the battery. Is it possbile to destroy a battery while flashing a ROM?

Same problem again:

Wow 40 views, and not a single idea?
Well I think I'm going to invest in a cradle, so that I can have both mains power and a usb connection, hopefully I'll be able to reflash with this. Anyone have expereince with this method? What is a good cradle?
i have t-mobile MDA and i was upgrading it to wm6 last night but i fall asleep while i'm doing that.
when i woke up this morning, my phone is dead and it won't come back on.
Please help me, guys!!!
is the battery fully discharged?
The battery is probably totalled.
The only way to wake it back up is to either (1) find someone with a battery with power in it, and figure out if you're only partially flashed, or (2) you can TRY the AC mains charger. It MAY be able to charge it.
The USB charger will not work unless the phone's firmware is intact, as the phone has to manage the charging request (for power) from the USB cable and without the logic functioning it won't ever ask for +5V to be sent down. USB negotiates power requirements.
The AC charger is just a dumb charger and MAY be able to do the job. If not, find someone else with an MDA and swap batteries with them - they will be able to "Wake" your dead battery with the AC charger in their phone, and you can then use the power to figure out what's up.
thanks, guys it came back on
but it stucked with bootloader screen, what should i do, now?
It has no firmware in it (or the load was interrupted)
Flash a valid firmware file. It will flash from the tri-color bootloader screen.
Hi guys,
So here's my list of problems i have encountered with my recently purchased asus tf701t (4 weeks back)
1 - the docking station doesn't charge since day one (although it's AD02, but from the october release), always at 0% with or without the tablet attached.Nor does it charge the tablet when its attached to it, rather drains its battery.
Even left it charging over night.
2 - 3 days back , vol up key stopped working without any apparent physical damage.
so far have tried:
contacting asus customer support without any positive solution, all they could come up with was that i do a "whip data" which i did to no avail.
currently the rom is stock rom JB 4.3, with latest US firmware and isn't rooted.
The problem am facing is i can't ship it back since i bought it online and paid a large amount for it to be shipped to my country, so shipping it back isn't an option for me.
PS: while the dock is connected to the wall charger and if i go into fastboot mode (power+vol down), the blinking of the 3 icons is painfully slow as compared to when i remove the charging cable. Also the docking station shows that its charging but actually drains the tablets battery instead.
so here's what am thinking will rooting and changing the firmware from US to ww be of any help?
Is there anything that can be done to fix the charging issue + the vol up key issue ?
also is there any way i could perform a triple whip data or cold boot without my vol up key working?
Please help me guys..............
Sounds like a hardware fault to me - I don't think rooting or installing a custom rom will help at all unfortunately.

Good question! I'm struggling to think of a way to do it as the volume up acts as the execute button......
hum... seems like am in a fix here. Not what i had expected from my first android tablet experience tbh.
Hope we get a work around for my vol up key problem which apparently had no problems 3 days back.
Another thing i have noticed is after three consecutive "factory rests" ,docking station when attached to a wall charger along with table "falsely" shows charging of tablet (instead it still keeps draining it battery) when its screen is off and goes back to not charging sign for tablet battery when it's screen is switched back on.
Throughout this time, the tablet battery shows its charging which it isn't. Also when the docking station is connected to wall charger independently it's charging (orange blinking led) does not light up....!!!:crying:
Hello!
ID: C5J8 BIOS: 2.05c
Symptom: if I shut down the tablet from Windows 10 or in Android 5.0 then I can't power on by button.
If I connect the USB cable afterwards it can be powered on random time - sometime after usb cable connect 5 minutes, sometimes more, it is very stochastic behaviour!
My question is: is it bug or feature? The reasen is settings in BIOS or what the hell, I dont understand? I have to tilt my family shut down the tablet, because they can't power on without me...
Do anybody have a good idea?
has nothing to do with windows or android for sure ... when the tab is in the S4 or S5 states the control of the tab is done by the BIOS firmware
1. do a restart/reboot from whatever OS and after that a power off and check whether is responsive now
2. do a forced power off (long press power btn until turns off) and check again
however if it did not show this behavior on your previous bios version then for sure is caused by something in the new bios (i would guess has something to do with the way the battery level is now detected, normally if your battery is below a level it will refuse to start, but if somehow the bios doesn't properly detect that...) maybe you can also try a 'load defaults' in the bios?
Have a look at this thread, it explains how the tablet determines when to turn on.
Dear wallabyman!
Thank you, it is very detailed and good post. I understand, and we can't do anything - it is a feature, but a very ugly feature from Teclast!
This time do you have any change in this operating? Could you power on by button after shut down?

It has operated in the same way with the original BIOS too!
The reason why I found the linked thread was because I am experiencing some problems too, although not as bad as you describe them.
I am able to always turn on the tablet. If it does not turn on, I am trying the following things (in no particular order):
- Make sure tablet is really off and not stuck with black screen, by holding power buton for 10-15 seconds to do a hard powerdown
- attach a USB lamp to USB-host adapter to see if it is still powered on
- let it charge for about 30 minutes with original charger and original cable before trying to turn on
- not move the USB charging cable too much, my device seems very sensitive to small changes in the USB charging connection. I have the tablet lying flat, and try to power on without touching the cable if it is charging at the same time
- set quiet boot to off in Bios to see the red AMI logo
a minor aspect:
- if the device is charging and I press the power button only once, the Bios boot screen will appear together with the battery, but will not boot until the power is pressed again and battery charge is sufficient
Sleeping:
- putting the device to sleep from Android (sikke1s ROM, not for your device) and waking up again seems to work perfectly for me now.
- with Windows I still have big issues, trying to narrow it down currently
- from the shutdown state I can always boot up within a few tries (press the button not too long or to short, try hard power off even if it appears to be off and again)
My Galaxy note 5 was working fine but I didn't use it for 2 years without charging and now every time when I plug the cable to charge the phone shows white screen for a minute then go to downloading mode and stuck there.
Please find the attachments.
I tried to reboot holding power button only nothing happened.
Then tried Vol down + power + home
I get black screen then downloading mode again,I tried to hold for too long I get the same but the different is some lines appearing on the top left corner.
Hard Reset Vol up + power + home (nothing happens)
I searched for solution and found a windows app can fix android phones but it need to be connected via USB cable.
When I plug the the cable to laptop it doesn't even make any tone that something was connected... like nothing happened.
I installed the driver but same issue.
Odin doesn't show anything too.
Not trying to blow you off. You would be better served asking this question in the Note 5 forum: https://forum.xda-developers.com/c/samsung-galaxy-note5.4429/
This is the Tab S7/S7 Plus forum.
Sorry ... how to delete this post?
I only can edit
Plug any usb capacity, voltage and amperage meter between the charger and the phone and see how much current the battery is taking in.
There are also chargers with an amp display.
A faulty battery can provoke this kind of behavior of the phone as in your case.
